Why Is My Plant Dropping Leaves? Common Causes and Solutions

Leaf drop is alarming but often fixable. The key is diagnosing the trigger — shock, water, weather, season, or pests. Here's a systematic checklist.

Top Causes of Leaf Loss

• Transplant/repot shock: #1 cause. Roots disturbed, environment changed. Minimize by keeping root ball intact, watering well, avoiding fertilizer for 2–3 weeks.
• Temperature swings: Sudden cold or heat → yellow/brown drop. Protect from drafts, heating vents, frost.
• Water extremes: Overwatering (yellow, mushy drop) or underwatering (crispy, curled drop). Check soil moisture before watering.
• Seasonal shedding: Normal! Broadleaf evergreens drop old leaves in spring; some trees in late summer. New growth follows.
• Pests/diseases: Inspect undersides for mites, scale, aphids; look for spots, mold, webbing.

Diagnosis Steps

1. Check soil moisture (finger test 2" down).
2. Inspect leaves top/bottom, stems, soil surface.
3. Review recent changes: move, repot, weather, watering.
4. Match symptoms to cause above.

Recovery

Correct the issue. Provide stable conditions. Don't overcorrect (e.g., don't flood a dry plant). Most plants releaf in 2–4 weeks if roots are healthy.

Patience + observation = diagnosis.
